1) For products with high molding temperatures, consider using a heater embedded in the hot nozzle body's hot runner to avoid the common heater expanding upon heating, leading to poor adhesion with the body and issues like uneven heating and heat loss.

2) The cores and runners of hot nozzles are made from selected materials and processed using special techniques, which enhance the surface hardness of the accessories, reduce the corrosion rate of the cores and nozzles caused by fire-resistant or corrosive materials, and extend the lifespan of the hot nozzles.

3) The分流板flow channels are polished with a special process, ensuring a smooth finish with no blind spots. This prevents the product from yellowing due to poor luster.
